Welcome to the Pennsylvania Mammal Atlas!

This is a project designed to collect valuable information on wild mammals within our Commonwealth. However, with 64 species and so much ground to cover, we need your help! Please consider becoming a Volunteer and submitting photographs of the mammals you observe. To see records submitted by others, visit the Observations page. If you need help identifying a mammal or you would like more information about a species, visit the Mammals page.
